Hey, honey, can I tag along?

From NBC's Domenico MontanaroForeign policy got its hands on a list of congressional delegations, or CODELS, over the August recess, which it published Thursday. And check out how many members are bringing spouses along.

Each spouse is listed as "No-cost to DoD." In other words, there are likely extra seats on the military planes that fly these members around the globe. And the questions become: Is there extra cost for them to stay in hotels? How do they pay for their meals? What excursions do they take? And, above all, what are the purposes of these trips in the first place?

Foreign Policy has the following reasons from its unconfirmed itinerary:

For Boehner's trip: "To discuss issues of mutual interest with government and private sector officials on issues related to global and regional economic performance and energy security."

For Cuellar's trip: "To investigate the critical security measures in place within these countries."

For Leahy's trip: To "conduct official British-American Parliamentary Group meetings."

For Costello's trip: "To meet with State and local officials to discuss port security and aviation maintenance issues."

Note, there are other trips -- McCain's and Kerry's, for example -- in which spouses don't tag along. Foreign Policy says that's "one sign the trip is tough."
